11B imaging with field-cycling NMR as a line narrowing technique
NMR imaging of 11B in a boric acid, B(OH)3, phantom has been done using a field-cycling NMR technique to narrow the 11B resonance. Field-cycling NMR combines the sensitivity of high-field detection with the narrow resonance of a pure NQR transition. In zero magnetic field, a very small rf coil is used as the method for spatially encoding the image by saturating the | ± 1 2 > → ||3/2 > transition for a selected region of the sample. In successive cycles the zero-field rf coil is translated step-wise along the sample. © 1993.
